Yes, the mighty 300 Avon rear tire hit the streets in early 2004. No bar room bullshit, this sucker is 12-inches wide. What does this mean? The massive size of the 300 rear tire makes left side drive obsolete - just a fact. Running this monster tire in a left side drive configuration would require a 3.25-inch left offset. Unless you plan on installing a sidecar on the right to counterbalance the weight offset, we don’t recommend using left side drive with the 300 tire.
We introduced RSD in 2001 when the 240 tires came out as a solution to balance big tire customs and it accomplished just that. More than ever with the 300 tire, RSD translates to zero offset and a perfectly balanced radical custom. See below for a short course in offset 101.

The Evo powered Harley Softail is the design basis for custom aftermarket components like frames, transmissions, and engines. The positional relationships between engine and transmission, engine and frame, and transmission and frame all go back to the Softail. The stock Softail from the factory is a well-balanced machine with no significant weight bias from the left to the right.
If a wider than stock rear tire is used on a Softail, the powertrain (engine and transmission) must be moved to the left to allow the 1-1/2-inch wide drive belt to clear the left side of the rear tire. Moving the powertrain to the left is referred to as powertrain offset. Powertrain offset can be achieved by moving the transmission and/or engine to the left, away from the stock position. The math to explain this is easy - see the figure to the left. The stock HD Softail has a 130 size rear tire that is roughly 5.5-inches wide. The 300 tire is roughly 12-inches wide, which means there is 3.25 more inches of rubber on each side. This pretty much means the powertrain has to move to the left 3.25-inch or so.BAKER DRIVETRAIN offers the RSD for these applications:
